To all whom, it nasty concern;- a

Beit known that we, GH ISTIANMAG E- PRANG, AUGUST FRIEDRICH PETERSEN, and- JiiRGEN F. MoLLER, subjects of the German Emperor, and residents of Kiel, Germ any,have invented a certain new and useful Improved HookforBoat-DetachingApparatus,of which the following is a specification.

The object of the present invention is a hook for boat-detaching apparatus or similar purposes where sudden detachment is required.

The hook consists, essentially, of two legs or sister hooks movable around a pivot and bent together to meet attheir ends and which can be opened or closed by means of a lever-With an eccentric boss pivoted. in an iron loop fixed on oneleg, the said boss having bearing against the outside of the other leg, tow ich the lever may also be connected by a short 7 link, the pin of which moves in a slot inthe eccentric boss of the lever. When thehook is closed, a slide engages into a recess in the eccentric to prevent the accidental opening of the hook. I I

The annexed drawings represent the'inven- Figure 1 is an elevation thereof, the full lines showing the hook when closed, and the dotted lines the same when open. Fig. 2 is a cross-section on the line 2 2 of Fig. 1. 1 l

This hook consists, essentially, of two-legs or sister hooks A A, movable around a pivot 1 and bent together to meet at their lower ends.

They can beopened or closed by means of a 3 5 lever H,moved"by hand withan eccentric boss E, pivoted in an iron loop B, fixed on one leg A of the said lever, the boss E'-having bearing against'the outside of the other leg A, to which it may also be connected by a 0 short link F, the pin G of which moves in a slot-J in the eccentric boss E of the lever H. When the hook is closed, a slide.D,moved by'hand, engages into -a recess 2' in the eccentric E to prevent the accidental opening 5 of the hook.

I The slide D is frictionally held in place by the spring 0. We claim as our invention In a hook for boat-detaching" apparatus or 50 other purposes the combination of two legs 7 A A pivoted together, a loop B attached to one leg, a lever H with eccentric boss E pivoted in said loop B and adapted to bear against leg A to closev the same and a slide 55 D adapted to engage a recess z of the eccentric boss E to prevent the accidental opening 7 of the hook substantially as described.

In witness whereof we have signed this specification in the presence of two witnesses. 6o
